Juniper Networks' NetScreen firewall is interoperable with Websense's proprietary filtering protocol to provide comprehensive web filterin g and web security functionality. As an employee accesses the Internet, the NetScreen firewall redirects the URL request to Websense, which completes a policy and database lookup. Websense returns a block/allow response to the NetScreen firewall for access to the requested URL while the Websense server logs the request for reporting purposes.
